Thanks for this. I really appreciate (and enjoyed!) the use cases. What I have in mind is mostly the information sharing use case. I think there's been a lot of focus on such a platform "catching on" and what it means on the global scale, and I did get caught up in that for a brief moment, but I've realised that my interest on the global scale is misplaced. I want something that primarily works for a local community, and I want it to be decentralised in a fashion so that if instances decide to acknowledge each-other's existence, they'll provide the ability to look for physically close posts by pointing to each other when relevant. This might not be how the rest of the Fediverse works, or want's to work, but it seems better and actually simpler in design to me. I think I'm going to go off and try building my own thing. If nothing else, it'll be a learning experience.
